Question

Suppose the probability of an event occurring is P(A), and the probability of the event not occurring is P(A'). If P(A) = m and P(A') = n, which of the following equations must be true?

A. m = 1 + n
B. n = 1 - m
C. n = m + 1
D. M =n -1

Answer 1

B

Explanation:

P(A)+P(A')=1

m+n=1

B is the only answer equal this if you add m to both sides.
